Since this concerns the issuance of an Irish visa, the requirements for such should be inquired from the Irish Consulate in Manila or through the Irish Naturalisation & Immigration Service (INIS):

The Philippine Consulate in Dublin cannot offer advise or intemperate of Irish immigration or naturalisation law or policy. 

 If the petitioner is required by the Irish Authorities to submit an affidavit of support, the petitioner should execute one and have it authenticated by the Philippine Consulate. A parental travel permit should also be executed by the petitioner and authenticated by the Philippine Consulate in Dublin.
